Studio för mekanik och hållfasthetslära - Tillverkning och utveckling av demonstrationsexperiment

Several studies have examined the effects of perceived justice of preferential treatments to customers, but few have studied these effects when customers have different input. The purpose of the study is therefore to enhance the knowledge and understanding of the effects of preferential treatments to customers with varying input. More specifically, the study focuses on how perceived justice, customer satisfaction and loyalty are affected depending on the customer's input and received treatment. An experimental study with 263 respondents showed that the perceived justice and loyalty intentions among both the receiver and the non-receiver of the preferential treatment were of highest level when it was given to a customer with large input. Customer satisfaction however, was found to be of highest level when customers themselves received preferential treatment, regardless of the size of their input.

Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

"Det är roligt!" : En studie om hur pedagoger använder estetiska lärprocesser i arbetet med naturvetenskap i förskolan

The purpose of this thesis is to investigate how teachers perceive that they work with science in preschool through aesthetic learning processes as tools both in the indoor and outdoor environment and make visible what the educators' underlying beliefs are that affect how they perceive aesthetic learning processes as tools used to deepen children's understanding of different scientific phenomena.This is an interview study using the phenomenographic approach as a means and method to make visible and report on teachers' views on how aesthetic learning processes can be used to extend preschool children's learning about science. The results are analyzed and discussed based on John Dewey's theoretical ideas about children's learning, aesthetics and science.The study clearly shows that teachers' views on aesthetic learning processes and how they can be used in the work whit science is very divided and in some cases unreflective. The most striking results are that teachers often are unaware that they make use of aesthetic learning processes because they have a more limited view of what it is than we have in the paper. All informants have science as a core subject. Their focus of the activity is located at the showing and visualizeing of scientific phenomena and some of them express that they submit the aesthetic learning processes to their colleagues or that they collaborate with someone who has training in some art form.

Kommunala webbplatser för alla eller några? : Kvalitativa intervjuer med webbansvariga i tio sydsvenska kommuner

There is a need for examining the accessibility of public web sites and for several reasons. First, public organizations possess considerable amounts information of interest to its citizens and which ought to be easily accessible. Secondly, international and national guidelines for web publishing support the different types of requirements experienced by web users and, in particular, with regard to accessibility for people with disabilities. The thesis examines the design of public web sites from two different aspects. Web sites can be built up and structured from the management view of the public organization, or, they can be constructed with a view to user needs and requirements.

Effekter av skendräktighet och kastration på tikens beteende

Pseudopregnancy is a condition that is estimated to affect 40 % of all female dogs. Common symptoms are decreased activity level, weight gain, mammary enlargement, milk production, nesting behavior, anorexia and maternal behavior. The symptoms are displayed during metoestrus. Prolactin is one of the causes behind pseudopregnancy, but the full process is not yet known. Due to the fact that the condition affects that many bitches and often is recurrent, it is relevant to examine how the condition affects the bitch?s behavior and performance.

Katalogisering och presentation av film på bibliotek

The aim of this thesis is to discuss selected parts of cataloguing both from a practical and a theoretical viewpoint. It presents the basic grounds for cataloguing of printed as well as non-printed materials. The focus lies on the main entry heading and its author/title problem concerning film. The thesis theoretical part consists of an analysis of central documents dealing with the author concept from both a library- and information science perspective and a film science perspective. The practical part consists of interviews from two Swedish public libraries, which have different approaches on presenting films.

Om socialdemokratins problem och möjligheter i ett individualiserat samhälle

We live in a society that has changed rapidly in recent years. The Swedish welfare state identity consisted of structures that had been formed from an emancipatory project. Today, these structures seem to have been erased and replaced by a different form of society. When a society is changing it affects the political, social and economic levels.In this social change Social Democracy seems to have lost its hegemonic position in society and describes itself as standing in a crisis. An effort to modernize the party has therefore begun.

Universeum är mer än ett komplement till den vanliga undervisningen

Science center har visat sig vara en utmärkt plats för undervisning. Detta är en studie av på vilket sätt ett skolbesök på ett science center kan bidra till att målen för år 9 uppnås och om ett besök på ett science center kan utgöra ett komplement till den vanliga skolundervisningen. Särskilt studeras ämnesområdet astronomi och kosmologi (universum och vårt solsystem) i ämnet fysik. Undersökningen är gjord på Universeum i Göteborg. Metoden i undersökningen är intervjuer och observationer.

Artbrott -en institutionell bastard i gränsskiktet mellan statsvetenskap och juridik?

This paper deals with a partly new development in the Swedish law system, somewhere in the boundary between political science and jurisprudence. A new instrument -artbrott- has successively become more popular among lawyers and politicians. The new instrument -here translated to classified crimes- signifies that the perpetrator is sentenced to prison even though the seriousness of the crime committed is not in itself serious enough for such a consequence. The reason for this policy stance is to create a prevention against crime of that specific character among the public. The use of this instrument has grown considerably both concerning types of crimes as well as in application.

En problemlösningsapplikation för Sveriges schackförbund

The purpose of this project was to investigate whether it was possible to develop a type of application, where users would solve chess problems. The main goal of the project was that there would exist an functional application after the study has ended with which users could solve chess problems on a computer. One subgoal of the project was to create corresponding application for mobile phones. The study was limited to require users to have at least Internet Explorer 9 +. For other browsers, there were no corresponding limitations.

När kultur var i rörelse : Kulturbegreppets förändring under sextiotalet, speglad genom tidskriften Ord&Bild

The aim of this thesis is to analyse and problematize the concept of culture and its changes during the 1960s. By examining articles out of the periodical Ord&Bild 1962-1972, I show how an aesthetically marked concept, closely related to the concept of art, changes into an anthropological perspective where attention is drawn to the social, economical, political and ideological aspects. This change is viewed in relation to the works of three prominent cultural theorists from the 1960s: Raymond Williams, Marshall McLuhan and Herbert Marcuse.The change that the concept of culture undergoes can be illuminated in several ways. Epistemologically questions of art, its objectivity and relation to reality, are replaced by questions of the function of art and of its role as reproducing ideas and norms of a bourgeois society. Economical and social aspects are used as critical factors in discussing the role and conception of culture, a perspective that gives the discussion a political and ideological edge.

Den psykosociala arbetsmiljöns betydelse och påverkan på ohälsan

This paper is about the psychosocial work environment, and those factors that can be responsible for an employee?s sick leave. We have through our knowledge from working life, on several occasions experienced colleagues becoming ill, the cause being the psychosocial working environment. Private factors, for instance different kinds of life crisis like a divorce or uprooting, have contributed to the sick leave. The psychosocial working environment is complex.

Problem inom systemutveckling - från ett genusperspektiv

Sammanfattning Systemutveckling är ett av de områden som snabbt har etablerat sig på marknaden. Trots detta faktum har inte själva utvecklingsprocessen förändrats nämnvärt under åren som gått. Samma problem som fanns beskrivet i böcker från början av 90-talet cirkulerar fortfarande inom detta område. Många av de problem som uppstår inom systemutveckling kan leda till system som inte fungerar på rätt sätt. Det kan även leda till högre kostnader och missnöjda kunder som i sin tur leder till lägre inkomster.

Varumärken och varningsetiketter: En kvantitativ studie i hur varningsetiketter påverkar personer då de är placerade på läskförpackningar och om varningsetiketternas effekt påverkas av varumärket

Warning labels can be used to change the attitude and behavior in the general public. The use of warning labels is also increasing and suggestions have been made to expand their use to more general food products. However, the research regarding the effects of warning labels and how other factors may influence them is limited.The purpose of this study was to develop the research on warning labels and the effects the strength of the brand might have on the warning label?s effect on more regular food products. To achieve this goal a 2x2 factorial design was used where over 200 respondents filled in four different forms.

Development of Liquid Cooling for PCs

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
